Different Types of Hydraulic Solenoid Directional Valve Blocks

Adopting a hydraulic solenoid directional valve allows the easy operation, and achieves to automate operations, so it is widely used in many fields. The work principle of an electromagnetic valve is to use the electromagnet driving spool to control the flow direction.

Due to valve spools vary in structures and types, there are slide valve, rotary valve, ball valve and cone valve, and according to the number of operating positiones and controlled channels on the valve block, the electromagnetic slide valve can be divided into two-position with two holes, two-position with three holes, two-position with four holes, three-position with four holes, three-position with five holes and other types. Usually a solenoid valve of two-position needs one electromagnet, and a three-position valve requires two electromagnets.
